Two Hand Linear Operation

These punches are similar except for punching capacity. Unlike other similar tools, these punches will punch and strip inside a 90° arc movement of the lever. And, the upper handle will not disengage when moved to either extreme.

Options include a bench mounting base, with a 3" - 3" 3/4" x 5" tapped base table; and a factory reversal of the upper handle to provide front pull-down operation when the tool's intended use is as a bench mounted unit.
